Forget channel surfing. These drunken couch potatoes thought it'd be fun to sofa surf instead, so they attached their couch to the bumper of an automobile and hit the streets of San Francisco. They made it surprisingly far (even through the Golden Gate Bridge!) before the police caught up with them. And their excuse for posing a threat to themselves and everyone around them is classic. If letter grades are involved, I'd give them a solid "D" for dumbass.
